SPECIFICATION forming part of Letters Patent No. 729,355, dated May 26,1903. Applicatiouled February 5, 1903. Serial No. 142,056. (Nomodel.)

- To all whom it may concern:

Be it known that l, ALEXANDER B. KILPAT- RIOK,a citizen of the UnitedStates of America, residing at Warren, in the county of Trumbull andState of Ohio, have invented certain new and useful Improvements inSap-Spouts, of which the following is a specification, reference beinghad therein to the accompanying drawings.

This invention relates to certain new and useful improvements insap-spouts, such as are employed to receive the sap from mapletrees andconduct the same from the opening which is bored in the tree to asuitable receptacle provided to receivethe same.

The object of the invention is to construct a sap-spout with a closedouter end, whereby the wind blowing against the outer end of the spoutmay not enter the same, which always tends to force the sap back intothe tree and prevent the free and ready flow thereof. NVhere the sap isdischarged from the end of the sap-spout, the wind has an uninterruptedentrance into the spout and tends to materially retard the flow of thesap; furthermore, the sap is in no wise protected from chill during thenight and ice frequently forms in the opening or bore in the tree,consequently preventing the llow of the sap until this ice has beenmelted. My invention obviates these difficulties, as it not only closesthe entrance to the spout against wind, but protects the sap againstfreezing in the spout or opening in the tree unless during a very lowtemperature. l

In describing' the invention in detail reference is had to theaccompanying drawings,

forming a part of this specification, andy wherein like numerals ofreference indicate like parts throughout the several views, in which-Figure l is a detail perspective view of the sap-spout constructed inaccordance with my invention. Fig. 2 is an inverted perspective Fig. 3is a rear end elevation of a modiiied construction. Fig. 4 is aperspective view showing the spout in position in the trunk of the tree.Fig. 5 is a crosssectional view of a modified construction.

My improved sap-spout is preferably made from a single piece of sheetmetal, which is drawn or rolled into tubular form and is tapered fromthe outer to the inner end, whereby the inner end l of the tubular spout2 is of considerably less diameter than the outer end 3. The edges'ofthe metal where the spout is made of a single piece of material arebrought together and secured, either by interlocking the same,soldering, or any other approved Ineans. The spout is closed at itsouter end by the head or disk 4, which may be soldered to the tubularspout or otherwise suitably secured thereto. The end l of the spout isadapted to be inserted in the bore or opening made therefor in thetree-trunk, and the spout, being tapered,it wedges securely in the saidbore or opening. An outlet-port 5 is made in the underneath face of thesanspout adjacent to the outer or closed end thereof. I preferablyprovide the spout with a hook or projection 6 on the upper face, overwhich the bail of the pail or other vessel to' receive the sap may beengaged. I may form Vthe spout in the manner shown in Figs. 3 and 5,wherein I employ two sheets of metal 7 and v8. These sheets of metal arerolled in the vtapering tubular form,'the same as shown in Figs. l and2, the sheet 7 having an inturned lip or flange 9 at one edge and thesheet 8 having an inturned lip or flange lO, which abuts against the lipor iiange 9. The solder may be run along the seam thus formed, ifdesired, though in both this construction and in the single-tubeconstruction shown in Figs. 1 and 2 the hook 6, which is usually made inthe form of a staple, serves to bind the edges of the blank together.This double wall or thickness of the body makes the same of considerablestrength, whereby it may be irmly driven into the opening or bore of thetree and will sustain a considerable'weight.

It will benoted that various changes may be made in the details ofconstruction without departing vfrom the general spirit of my invention.

Having fully described my invention, what I claim as new,.and desire tosecure by Letters Patent, is

Adevice of the type set forth comprising a In testimony whereof I aiix4my signature tapering,r tubular body open at one end, and in thepresence of two Witnesses. provided with tu openin r in its Walls near wthe larger end thereof, disk closing the ALEXANDER B' KILPATRICK 5larger end of the body and a hook centrally Witnesses:
